MetalMan,
Got a quick question on this topic though I am a long way from applying any answer. My cab floor and toeboard are in very sad shape; tears, half-assed repairs with fiberglass, etc. Additionally both front cab mounts were rusted and one side had torn up through the floor (cab tilted quite nicely, thank you

). Cab was taken off of the frame along with everything else and is now sitting on a cab dolly that I built. My plan, when I get to that point, was to put the doors back in the cab while still on the dolly and use wedges, spacers, whatever to align the doors. I was then going to roll the cab onto it's back and then replace the floor and toeboard. What do you think? Would you recommend a different approach? Thanks for any advice you can give me.
